+# Eval Framework Implementation Plan
+
+## Goal
+
+Build `uwf-eval` CLI + eval task infrastructure for evaluating uwf workflow quality with real agents.
+
+## Architecture
+
+```
+uwf-eval (runner)          task package (npm)          OCAS (storage)
+  │                          │                           │
+  ├─ unpack tarball ───────► fixture/ → tmp cwd          │
+  ├─ read task.yaml          │                           │
+  ├─ uwf thread start/exec  │                           │
+  ├─ run judges ───────────► dist/judges/*.js            │
+  ├─ collect scores          │                           │
+  └─ store results ─────────────────────────────────────► CAS nodes + variables
+```
+
+### Key Design Decisions
+
+- **uwf-eval is NOT part of uwf** — separate package, shells out to uwf CLI
+- **Task = npm package** — fixture + task.yaml + judge scripts, distributable as tarball
+- **Judge = Node script** — `node <entry> <cwd> <thread-id>`, outputs `{score, data}` JSON
+- **Every output is OCAS typed** — eval-run, judge results all have registered schemas
+- **Builtin judges** — frontmatter compliance, upstream consumption, hallucination, token stats
+- **Task-specific judges** — bundled in the task package, custom schema per judge
+
+## Deliverables
+
+### Phase 1: Foundation (`@united-workforce/eval`)
+
+New package in the uwf monorepo.
+
+```
+packages/eval/
+  src/
+    cli.ts                    # uwf-eval entry point
+    commands/
+      run.ts                  # uwf-eval run
+      report.ts               # uwf-eval report <hash>
+      diff.ts                 # uwf-eval diff <hash> <hash>
+      list.ts                 # uwf-eval list
+    runner/
+      prepare.ts              # unpack tarball/dir → tmp cwd
+      execute.ts              # shell out to uwf thread start/exec
+      collect.ts              # run judges, collect scores
+    judge/
+      types.ts                # JudgeInput, JudgeOutput types
+      builtin/
+        frontmatter.ts        # frontmatter compliance check
+        upstream.ts           # upstream info consumption (LLM-as-judge)
+        hallucination.ts      # hallucination detection (LLM-as-judge)
+        token-stats.ts        # token usage from $usage field (#68)
+    storage/
+      schemas.ts              # OCAS schema definitions
+      store.ts                # CAS read/write helpers
+      index.ts                # variable indexing (@uwf/eval/*)
+    task/
+      types.ts                # TaskManifest type (task.yaml)
+      loader.ts               # parse task.yaml, validate
+  package.json
+  tsconfig.json
+```
+
+#### OCAS Schemas to Register
+
+1. `@uwf/eval-run` — full eval execution record
+   ```
+   { task, config: {agent, model, engineVersion}, threadId,
+     judges: [{name, score, weight, dataHash}], overall, timestamp }
+   ```
+
+2. `@uwf/eval-judge-frontmatter` — frontmatter judge data
+   ```
+   { stepsTotal, stepsValid, invalidSteps: [{stepIndex, role, errors: string[]}] }
+   ```
+
+3. `@uwf/eval-judge-upstream` — upstream consumption judge data
+   ```
+   { perStep: [{role, consumed: string[], missed: string[], score}] }
+   ```
+
+4. `@uwf/eval-judge-hallucination` — hallucination judge data
+   ```
+   { perStep: [{role, hallucinations: string[], score}] }
+   ```
+
+5. `@uwf/eval-judge-token-stats` — token stats (not scored, informational)
+   ```
+   { totalInput, totalOutput, totalTurns, perStep: [{role, input, output, turns, duration}] }
+   ```
+
+#### CLI Design
+
+```bash
+# Run eval
+uwf-eval run <task-dir-or-tarball> [--agent hermes] [--model claude-sonnet-4] [--count 20]
+
+# View results
+uwf-eval report <run-hash>        # render via ocas render
+uwf-eval diff <hash1> <hash2>     # side-by-side comparison
+uwf-eval list                     # list past runs
+```
+
+### Phase 2: Task Package Scaffold
+
+Template for creating eval tasks. Also serves as the first real task.
+
+```
+eval-tasks/                        # shazhou/uwf-eval-tasks monorepo
+  packages/
+    _template/                     # copypaste template
+      package.json
+      task.yaml
+      fixture/
+      src/judges/
+      tsconfig.json
+    fix-off-by-one/                # first real task
+      package.json                 # @uwf-eval/fix-off-by-one
+      task.yaml
+      fixture/
+        src/calc.ts                # buggy calculator
+        src/calc.test.ts           # test that exposes the bug
+        package.json
+      src/judges/
+        test-pass.ts               # runs pnpm test, checks exit code
+        code-quality.ts            # LLM judge: minimal change, correct fix
+      schemas/
+        test-pass.json             # OCAS schema for test-pass data
+        code-quality.json          # OCAS schema for code-quality data
+      tsconfig.json
+  pnpm-workspace.yaml
+  tsconfig.json
+  biome.json
+```
+
+#### task.yaml Format
+
+```yaml
+name: fix-off-by-one
+description: Fix an off-by-one error in a calculator's add function
+workflow: solve-issue              # registered workflow name, or relative path to .yaml
+prompt: "Fix the bug: add(1,2) returns 4 instead of 3"
+limits:
+  maxSteps: 15
+  timeoutMinutes: 30
+judges:
+  - name: frontmatter-compliance
+    weight: 0.15
+    builtin: true
+  - name: upstream-consumption
+    weight: 0.15
+    builtin: true
+  - name: hallucination
+    weight: 0.1
+    builtin: true
+  - name: token-stats
+    weight: 0                      # informational, not scored
+    builtin: true
+  - name: test-pass
+    weight: 0.3
+    entry: dist/judges/test-pass.js
+    schema: schemas/test-pass.json
+  - name: code-quality
+    weight: 0.3
+    entry: dist/judges/code-quality.js
+    schema: schemas/code-quality.json
+```
+
+#### Judge Script Contract
+
+```typescript
+// Input: process.argv = [node, script, cwd, threadId]
+// Output: stdout JSON
+// Exit 0 = success, non-zero = judge error (not low score)
+
+import type { JudgeOutput } from "@united-workforce/eval";
+
+const result: JudgeOutput<TestPassData> = {
+  score: 1.0,      // 0.0 - 1.0
+  data: {           // typed per judge schema
+    command: "pnpm test",
+    exitCode: 0,
+    output: "3 tests passed"
+  }
+};
+
+console.log(JSON.stringify(result));
+```
+
+### Phase 3: Prerequisite — $usage in Adapter Protocol (#68)
+
+Blocked by #68. Token stats judge needs `$usage` in step nodes.
+
+Can proceed with Phase 1+2 without it — token-stats judge just returns zeros until adapters report usage.
+
+## Implementation Order
+
+1. **Phase 1a**: `@united-workforce/eval` package scaffold + CLI skeleton + OCAS schemas
+2. **Phase 1b**: `run` command — prepare, execute, collect flow
+3. **Phase 1c**: Builtin judges — frontmatter (deterministic), upstream + hallucination (LLM-as-judge)
+4. **Phase 2a**: Create `shazhou/uwf-eval-tasks` monorepo with proman
+5. **Phase 2b**: First task `fix-off-by-one` with fixture repo + 2 custom judges
+6. **Phase 2c**: End-to-end test: `uwf-eval run packages/fix-off-by-one --agent hermes`
+7. **Phase 1d**: `report`, `diff`, `list` commands (read from CAS, render via ocas render)
+
+## Dependencies
+
+- `@ocas/core` + `@ocas/fs` — CAS storage
+- `@united-workforce/protocol` — step node types
+- `commander` — CLI framework (consistent with uwf)
+- LLM API access — for LLM-as-judge (upstream, hallucination, task-specific quality judges)
+
+## Open Questions
+
+1. **LLM-as-judge provider config** — reuse uwf's `~/.uwf/config.yaml` provider settings? Or separate config?
+2. **Workflow file location** — task.yaml references a workflow. Should the workflow YAML be inside the tarball, or reference a registered workflow by name?
+3. **Non-coding tasks** — debate workflow has no fixture repo. task.yaml needs `fixture: null` or simply omit the `fixture/` dir. Runner creates empty cwd.
+4. **Parallel judge execution** — judges are independent, can run in parallel. Worth the complexity?
+
+## Risks
+
+- LLM-as-judge consistency — same input may get different scores. Mitigation: run judge multiple times, take average? Or accept variance.
+- Token cost of judges — each LLM judge call costs tokens. For a 10-step workflow with 2 LLM judges = 20 LLM calls just for judging. Acceptable?
+- Fixture repo drift — if the fixture evolves, old eval runs become non-comparable. Pin fixture version in task.yaml.

-      On first run (no previous steps):
-      1. Read the issue and all comments from Gitea using `tea issues <number> -r <owner/repo>`
-      2. Look for project conventions files (CLAUDE.md, CONTRIBUTING.md, .cursor/rules/) in the repo
-      3. Assess whether the issue has enough information to produce a test spec
-      4. If insufficient info: comment on the issue via `echo "..." | tea comment <number> -r <owner/repo>` (skip if you already commented), then output $status=insufficient_info
-      5. If sufficient: produce a detailed TDD test spec in markdown covering all scenarios
-
-      On subsequent runs (bounced back by tester with fix_spec):
-      1. Read the tester's output from the previous step to understand what's wrong with the spec
-      2. Revise the test spec accordingly
-
-      After producing the test spec:
-      1. The test spec is stored in CAS automatically by the uwf pipeline (agents do not need to call `ocas put` directly)
-      2. Put the plan hash in frontmatter.plan (required when $status=ready)
-      3. Set repoPath to the absolute path of the repository root
-
-      IMPORTANT: Extract the repo remote (owner/repo) from git:

-      IMPORTANT: Always work in a git worktree, NEVER modify the main working directory directly.
-      The repo path and other details are provided in your task prompt.
-
-      Before starting any work, set up an isolated worktree:
-      1. cd into the repo path provided in your task prompt
-      2. `git fetch origin` to get latest refs
-      3. First time (no existing branch):
-         - `git worktree add .worktrees/fix/<issue-number>-<short-slug> -b fix/<issue-number>-<short-slug> origin/main`
-         - `cd .worktrees/fix/<issue-number>-<short-slug> && bun install`
-      4. If bounced back from reviewer or tester (branch already exists):
-         - cd into the existing worktree under `.worktrees/fix/<issue-number>-<short-slug>`
-         - `git fetch origin && git rebase origin/main`
-      5. ALL subsequent work must happen inside the worktree directory.
-
-      Then implement TDD:
-      6. Read the test spec from CAS: `ocas get <plan hash>` (find the hash from the planner's output in your task prompt)
-      7. If bounced back from reviewer or tester: read the previous role's feedback in your task prompt
-      8. Write tests first based on the spec
-      9. Implement the code to make tests pass
-      10. Ensure `bun run build` passes with no errors
-      11. Run `bun test` to verify all tests pass
-          - If tests fail on first run:
-            * Read the test output carefully for missing imports or setup issues
-            * Check if you're running tests from the correct working directory (package root vs workspace root)
-            * Fix the immediate issue and rerun ONCE
-            * If tests still fail after 2 attempts: check the test spec for ambiguities
-            * If stuck after 3 test cycles: set $status=failed with detailed error report rather than continuing blind retries
-      12. MANDATORY VERIFICATION before reporting done:
-          - Run `git branch --show-current` and confirm branch name matches expected
-          - Run `git status` and verify changed files exist
-          - Run `ls -la <key-implementation-files>` to verify they exist on disk
-          - If ANY verification fails: retry the implementation, do NOT report done
-
-      If you cannot complete the implementation (e.g. the issue is too complex, blocked by external factors,
-      or repeated attempts fail), set $status=failed with a reason.

-         - If the cd succeeds: proceed with step 1 below
-      1. Run `git branch --show-current` — confirm the branch name references the issue number being worked on
-      2. If the branch doesn't correspond to the issue, flag it in your output and reject

-      Then perform code review:
-      Hard checks (must all pass):
-      3. `bun run build` — no build errors
-      4. `bunx biome check` — no lint violations

-      1. Check `git status` — if working tree is clean and branch is ahead of origin, skip to step 3 (push).
-      2. If there are unstaged/uncommitted changes: `git add -A` then `git commit -m "type: description\n\nFixes #N"`
-      3. Push the branch: `git push -u origin <branch-name>`
-      4. **Verify push succeeded** — run `git ls-remote origin <branch-name>` and confirm it prints a commit hash.
-         - If no output or push failed: capture the error, mark hook_failed
-      5. Create a PR using the Gitea API (do NOT use `tea pr create` — it fails in worktrees):

-         - The repo remote (owner/repo format, e.g. "shazhou/united-workforce") is given in your task prompt — use it directly.
-         - PR body must include: What / Why / Changes / Ref sections, with `Fixes #N` in Ref
-      6. **Verify PR was created** — parse the curl response JSON: it must contain a `"number"` field. Print the PR URL.
-         - If curl returns an error or no number field: capture the response, mark hook_failed
-      7. After PR creation, clean up the worktree:
-         - cd to the repo root (parent of .worktrees)
-         - `git worktree remove <worktree-path>`

+
+### Packages
+
+- **@united-workforce/protocol** — shared types (WorkflowPayload, StepNode, etc.)
+- **@united-workforce/util** — Crockford Base32, ULID, structured logger, frontmatter parsing
+- **@united-workforce/util-agent** — agent factory, context builder, extract pipeline
+- **@united-workforce/cli** — `uwf` CLI (thread lifecycle, status-based moderator, workflow registry)
+- **@united-workforce/eval** — `uwf-eval` CLI (prepare → execute → collect eval pipeline)
+- **@united-workforce/agent-hermes** — `uwf-hermes` adapter (Hermes Agent)
+- **@united-workforce/agent-claude-code** — `uwf-claude-code` adapter (Claude Code CLI)
+- **@united-workforce/agent-builtin** — `uwf-builtin` adapter (built-in LLM agent)

+
+### Highlights
+
+- Status-based graph routing (no LLM moderator cost)
+- CAS-backed immutable thread chains (`@ocas/core`)
+- Real token usage tracking (Hermes + Claude Code)
+- Eval framework with built-in judges (frontmatter, token-stats, test-pass)
+- `$SUSPEND` / resume for human-in-the-loop workflows

+      ## Critical Thinking Framework (execute before every speech)
+
+      ### A. Pre-speech reflection (internal, do not output)
+      - Does every step in my argument chain hold? Any hidden assumptions or logical gaps?
+      - If I were my opponent, how would I attack this? Where am I weakest?
+      - Does my evidence actually support my claim, or could it backfire?
+      - Should I go on offense or defense this round?
+
+      ### B. Evidence discipline
+      - Verify key numbers — watch for order-of-magnitude errors
+      - Assess data freshness — fast-moving fields have short half-lives
+      - Distinguish primary data from secondary citations, expert opinion, and common assumptions
+
+      ### C. Anti-fragility
+      - Anticipate counterarguments; preemptively strengthen or strategically abandon weak points
+      - Catch logical gaps, data misuse, or outdated claims in your opponent's reasoning
+
+      ## Rules
+      1. Check Thread Progress to see how many times you have spoken.
+      2. On your 3rd speech, you MUST output $status: final (closing statement).
+      3. If genuinely convinced by the opponent, output $status: conceded.
+      4. Otherwise output $status: speak and counter the opponent's points.

+- fix: decouple session resume from isFirstVisit guard
+  
+  When frontmatter validation fails, the step is never written to CAS, so isFirstVisit remains true on the next run. Both adapters now always check the session cache regardless of isFirstVisit. When resuming after a frontmatter-only failure (isFirstVisit + cache hit), a minimal correction prompt is sent via buildFrontmatterRetryPrompt() instead of re-sending the full initial prompt.

+- 8085d1d: fix: read token usage from ACP PromptResponse instead of DB
+
+  Token counts (inputTokens, outputTokens) now come from the ACP
+  `PromptResponse.usage` field, which is populated synchronously from
+  `run_conversation()` return data — no WAL race condition.
+
+  Turns (assistant message count) still come from the DB via
+  `snapshotTurns()` before/after delta.
+
+  Previously both tokens and turns were read from the Hermes state DB
+  after the ACP prompt returned, but due to WAL write lag the DB often
+  had incomplete token data at read time (e.g. 235 vs actual 26,080).

+### Patch Changes

+- 850a3b2: fix: resolve --agent override via config alias before raw command
+
+  `resolveAgentConfig()` now checks `config.agents[alias]` first before falling back to `parseAgentOverride()`. Eval CLI default `--agent` changed from `"hermes"` to `"uwf-hermes"`.

+Set up or upgrade uwf (United Workforce) — from zero to running your first workflow.
 
-You are being asked to install or update the uwf (United Workforce) skill
-so that you know how to use the \`uwf\` CLI for workflow orchestration.
+## Scenario A: Fresh Install
 
-## Steps
+### Step 0 — Environment pre-flight check
+
+Run ALL checks below BEFORE installing anything. If any check fails, fix it first — do NOT skip ahead.
 
-1. **Check if uwf CLI is installed:**
 \`\`\`bash
-   uwf --help
-   \`\`\`
-   If not installed: \`bun add -g @united-workforce/cli\`
+# 1. Node.js
+node --version   # need v20+
+# FIX: install via nvm (https://github.com/nvm-sh/nvm) or your OS package manager
 
-2. **Clean up old versions of the skill** (if any exist):
-   - Look for any existing uwf/workflow skill files in your skill directories
-     (e.g. \`~/.hermes/skills/uwf/SKILL.md\` or similar paths).
-   - If a skill exists, read its \`version\` from the YAML frontmatter.
-   - If the version matches the current CLI version (\`uwf --version\`), you're done — no update needed.
-   - If the version is older, **delete the old skill file** before proceeding.
+# 2. Package manager — pnpm (preferred) or npm
+pnpm --version || npm --version
+# FIX for pnpm: corepack enable pnpm   (Node 20+)
+#   or: npm install -g pnpm
+# If pnpm is not an option, npm works too — adjust install commands below
 
-3. **Get the usage skill content:**
-   \`\`\`bash
-   uwf prompt usage
+# 3. Global bin directory is in PATH
+# For pnpm:
+pnpm bin -g       # prints the global bin directory
+# For npm:
+npm prefix -g     # global prefix; bin is <prefix>/bin
+# The directory printed above MUST be in your PATH.
+# Test: echo \\$PATH | tr ':' '\\\\n'
+# FIX: add the missing directory to your shell's startup file
+#   (e.g. ~/.bashrc, ~/.zshrc, ~/.profile, or fish config):
+#   export PATH="<global-bin-dir>:$PATH"
 \`\`\`
 
-4. **Create a SKILL.md file** in your skill directory (e.g. \`~/.hermes/skills/uwf/SKILL.md\`).
-   The output of \`uwf prompt usage\` is the skill body WITHOUT frontmatter.
-   You must prepend the following YAML frontmatter:
+**All checks must pass before continuing.** If you had to modify PATH, verify the change persists by opening a new shell or sourcing your shell config.
 
+### Step 1 — Discover agents and install adapter
+
+**First, detect which supported agents are already installed on the user's machine:**
+
+\`\`\`bash
+# Check for Hermes Agent
+which hermes 2>/dev/null && hermes --version
+
+# Check for Claude Code
+which claude 2>/dev/null && claude --version   # should show "X.Y.Z (Claude Code)"
+\`\`\`
+
+**Based on the results:**
+
+- **Only hermes found** → install \`uwf-hermes\` adapter
+- **Only claude found** → install \`uwf-claude-code\` adapter
+- **Both found** → ask the user which agent they want uwf to use as default
+- **Neither found** → the user must install at least one agent first:
+  - Hermes Agent: https://hermes-agent.nousresearch.com/docs
+  - Claude Code: \`npm install -g @anthropic-ai/claude-code\`
+
+**Install the uwf CLI and the chosen adapter** using pnpm or npm:
+
+\`\`\`bash
+# CLI (required)
+pnpm add -g @united-workforce/cli       # or: npm install -g @united-workforce/cli
+
+# Adapter — install the one matching the detected agent:
+pnpm add -g @united-workforce/agent-hermes       # or: npm i -g @united-workforce/agent-hermes
+pnpm add -g @united-workforce/agent-claude-code   # or: npm i -g @united-workforce/agent-claude-code
+\`\`\`
+
+**⚠ Adapter versions are independent from CLI versions.** Do NOT try to match adapter version to CLI version. Just install \`@latest\` (the default).
+
+**After installing, verify that \`uwf\` and the adapter are available in PATH:**
+
+\`\`\`bash
+uwf --version          # should print ${CLI_VERSION}
+uwf-hermes --version   # or: uwf-claude-code --version
+\`\`\`
+
+If either command is not found, the global bin directory is not in the current shell's PATH. **You must fix this before continuing:**
+
+1. Find where the binary was installed:
+   \`\`\`bash
+   find ~/.local ~/.hermes /usr/local -name uwf -type f 2>/dev/null
+   npm prefix -g    # global prefix — bin is <prefix>/bin
+   \`\`\`
+2. Add the directory to PATH permanently by appending to the user's shell config (e.g. \`~/.bashrc\`, \`~/.zshrc\`, \`~/.profile\`, or fish config):
+   \`\`\`bash
+   export PATH="<global-bin-dir>:$PATH"
+   \`\`\`
+3. Source the updated config or open a new shell, then re-verify the commands work.
+
+**uwf-hermes** also requires the Hermes ACP plugin. Verify with \`hermes acp --help\`. If not available, install it:
+\`\`\`bash
+# Option A: install into hermes venv (recommended)
+source ~/.hermes/hermes-agent/.venv/bin/activate && pip install hermes-agent[acp]
+
+# Option B: pipx
+pipx install 'hermes-agent[acp]'
+
+# Option C: if installed from source
+pip install -e '.[acp]'
+\`\`\`
+
+### Step 2 — Configure provider and model
+
+uwf needs an LLM provider to run agents. **Ask the user** for their provider, API key, and model, then run:
+
+\`\`\`bash
+uwf setup --provider <name> --api-key <key> --model <model> --agent <adapter-command>
+\`\`\`
+
+**Note:** \`--agent\` takes the adapter **command name** (e.g. \`uwf-hermes\`), not the npm package name.
+
+**Preset providers** — when using a preset name, \`--base-url\` is auto-filled and can be omitted:
+
+| Provider | Name | Default base URL |
+|----------|------|-----------------|
+| OpenAI | \`openai\` | https://api.openai.com/v1 |
+| xAI | \`xai\` | https://api.x.ai/v1 |
+| OpenRouter | \`openrouter\` | https://openrouter.ai/api/v1 |
+| Venice | \`venice\` | https://api.venice.ai/api/v1 |
+| Dashscope | \`dashscope\` | https://dashscope.aliyuncs.com/compatible-mode/v1 |
+| DeepSeek | \`deepseek\` | https://api.deepseek.com/v1 |
+| SiliconFlow | \`siliconflow\` | https://api.siliconflow.cn/v1 |
+| VolcEngine | \`volcengine\` | https://ark.cn-beijing.volces.com/api/v3 |
+| Kimi (Moonshot) | \`kimi\` | https://api.moonshot.cn/v1 |
+| GLM (Zhipu AI) | \`glm\` | https://open.bigmodel.cn/api/paas/v4 |
+| StepFun | \`stepfun\` | https://api.stepfun.com/v1 |
+| MiniMax | \`minimax\` | https://api.minimax.io/v1 |
+| Ollama (local) | \`ollama\` | http://localhost:11434/v1 |
+
+For **non-preset providers**, you must specify \`--base-url\` manually.
+
+Example:
+\`\`\`bash
+uwf setup --provider openrouter --api-key sk-or-... --model anthropic/claude-sonnet-4 --agent uwf-hermes
+\`\`\`
+
+If the user doesn't know what to choose, suggest \`openrouter\` with \`anthropic/claude-sonnet-4\` as a sensible default.
+
+Config is saved to \`~/.uwf/config.yaml\`. Verify with \`cat ~/.uwf/config.yaml\`.
+
+### Step 3 — Install skills
+
+Run each command and create a skill from its output:
+
+\`\`\`bash
+uwf prompt usage               # → save as skill "uwf-usage"
+uwf prompt workflow-authoring  # → save as skill "uwf-workflow-authoring"
+uwf prompt adapter-developing  # → save as skill "uwf-adapter-developing"
+\`\`\`
+
+Each command outputs a complete SKILL.md with YAML frontmatter. Use your agent framework's skill creation API to save them (e.g. \`skill_manage(action='create', name='uwf-usage', content=<output>)\`).
+
+Verify skills are installed by listing them (e.g. \`skills_list()\`) and confirming all three appear.
+
+**⚠ After saving all skills, start a new session** so the agent loads the updated skill content. Skills saved in the current session are not active until the next session.
+
+### Step 4 — Verify end-to-end
+
+Create a minimal workflow file to test your setup:
+
+\`\`\`bash
+cat > /tmp/hello.yaml << 'YAML'
+name: hello
+description: Minimal smoke test
+roles:
+  greeter:
+    description: "Greet the user"
+    goal: "Respond with a friendly greeting"
+    capabilities: []
+    procedure: "Write a short greeting based on the prompt."
+    output: "A greeting message."
+    frontmatter:
+      type: object
+      properties:
+        $status: { const: done }
+        message: { type: string }
+      required: [$status, message]
+graph:
+  $START:
+    new: { role: greeter, prompt: "Say hello to the user." }
+    resume: { role: greeter, prompt: "Greet the user again." }
+  greeter:
+    done: { role: "$END", prompt: "Done." }
+YAML
+\`\`\`
+
+Then run:
+
+\`\`\`bash
+uwf thread start /tmp/hello.yaml -p "Hello, world!"
+uwf thread exec <thread-id>
+uwf thread show <thread-id>
+\`\`\`
+
+If the thread reaches \`$END\` with status \`completed\`, the setup is working.
+
+## Scenario B: Upgrade from Previous Version
+
+### Step 1 — Update packages
+
+\`\`\`bash
+# Using pnpm
+pnpm add -g @united-workforce/cli@latest
+
+# Using npm
+npm install -g @united-workforce/cli@latest
+\`\`\`
+
+\`\`\`bash
+uwf --version   # should print ${CLI_VERSION}
+\`\`\`
+
+Also update your adapter(s):
+
+\`\`\`bash
+# pnpm
+pnpm add -g @united-workforce/agent-hermes@latest
+
+# npm
+npm install -g @united-workforce/agent-hermes@latest
+\`\`\`
+
+### Step 2 — Regenerate skills
+
+Skill content is bundled with the CLI — always regenerate after upgrading:
+
+\`\`\`bash
+uwf prompt usage               # → update skill "uwf-usage"
+uwf prompt workflow-authoring  # → update skill "uwf-workflow-authoring"
+uwf prompt adapter-developing  # → update skill "uwf-adapter-developing"
+\`\`\`
+
+**⚠ After updating skills, start a new session** to load the new skill content.
+
+### Step 3 — Migrate workflow YAML files (if needed)
+
+Check the changelog for breaking changes. Known migrations:
+
+- **v0.2.0**: \`$START._\` → \`$START.new\` + \`$START.resume\`. All workflow YAML files must be updated:
   \`\`\`yaml
-   ---
-   name: uwf
-   description: "Use when orchestrating multi-agent workflows with uwf (United Workforce). Covers CLI usage, workflow YAML authoring, moderator logic, and agent development."
-   version: <VERSION>
-   author: United Workforce
-   license: MIT
-   metadata:
-     hermes:
-       tags: [workflow, agents, orchestration, cli, yaml]
-   ---
+  # Before (v0.1.x)
+  $START:
+    _: { role: planner, prompt: "..." }
+
+  # After (v0.2.0+)
+  $START:
+    new: { role: planner, prompt: "..." }
+    resume: { role: planner, prompt: "Review previous run and continue." }
   \`\`\`
 
-   Replace \`<VERSION>\` with the installed CLI version (from \`uwf --version\`).
+Update all \`.workflow/\` and \`.workflows/\` YAML files in your projects. \`uwf workflow add\` will reject files with the old \`_\` syntax.
 
-5. **Verify** the skill is loadable by your agent framework.
+- **v0.2.1**: \`$status: { enum: [value] }\` → \`$status: { const: "value" }\`. The validator no longer accepts \`enum\` for \`$status\`. Update all workflow YAML files:
+  \`\`\`yaml
+  # Before (v0.2.0)
+  $status: { enum: [done] }
+  $status: { type: string, enum: ["ready", "failed"] }
 
-## Individual prompts
+  # After (v0.2.1+)
+  $status: { const: "done" }
+  # For multi-exit, use oneOf with const (unchanged)
+  \`\`\`
 
-You can also get individual reference sections:
+### Step 4 — Verify
+
+\`\`\`bash
+uwf thread start <your-workflow> -p "upgrade test"
+uwf thread exec <thread-id>
+\`\`\`
+
+## Available prompts
 
 \`\`\`bash
 uwf prompt list                # list available prompt names
-uwf prompt user                # user reference (CLI guide + typical workflows)
-uwf prompt author              # author reference (workflow YAML design guide)
-uwf prompt developer           # developer reference (coding conventions + architecture)
-uwf prompt adapter             # adapter reference (building agent adapters)
-uwf prompt bootstrap           # bootstrap skill YAML for Hermes agents
+uwf prompt usage               # CLI usage guide
+uwf prompt workflow-authoring  # workflow YAML design guide
+uwf prompt adapter-developing  # building agent adapters
+uwf prompt bootstrap           # this guide
 \`\`\`
-
-## Notes
-
-- The skill content is bundled with the CLI and versioned with it — always use
-  \`uwf prompt usage\` to get the content matching your installed version.
-- Do NOT hand-edit the skill body. If the CLI is updated, re-run \`uwf prompt setup\`
-  and follow the steps again.
-- When upgrading, always delete the old skill first to avoid stale instructions.

+- 850a3b2: fix: resolve --agent override via config alias before raw command
+
+  `resolveAgentConfig()` now checks `config.agents[alias]` first before falling back to `parseAgentOverride()`. Eval CLI default `--agent` changed from `"hermes"` to `"uwf-hermes"`.
